Somewhere on the board there was info on how low flow limitations (FL) be, I could not find it. Sorry.
Unofficially, I would say up pressure until they stop, without increasing central events. If FL causes issues then that is to many.

Usually, flow limitations are controlled by increasing Pressure Support (or EPR) rather than Pressure. That may increase the CA, so it can be a balancing act.

Steve,
Usual titration method for CPAP (not including centralapnra) EPR comfort setting – Set to patient comfort (1, 2 or 3) Increase CPAP ≥1 cm H2O every ≥5 mins for obstructive apneas, hypopneas, RERAs and at least 3 min of loud or unambiguous snoring Up minimum pressure to 12 cm.

@ Old Steve
Hi, haven't checked onyour progress for some time.. Firstly your charts are excellent. Well calibrated, and I don't think you can do much bettter. You seem somewhat concerned about FLs with "the Fl's range from 0.7 to 0.11.", in fact if you look again at yout charts, the values are from .07 to 0.11! I would suggest that you focus on the up to 95% values, which are actuallygreat. The up to 99.5% values include the "marginal" events. I haven't tried to calculate the duration values (in secs.) of these marginal events, but guess in the scheme of things they are irrelevant and create a false debate. I would relax on this subject. I can't remember the correct wording for this phrase, but it is something like this:- "Don't try to fix something that ain't broke!" You have done extremely well in such a short time. I have quite a similar profile to you, in that short of sleep hours in spite of a well calibrated CPAP. My average is only about 6 hours at best. This I put down to being retired for quite a few years and being without the mental stimulation of the working life; and the pain from side sleeping due to some residual chronic pain from an operation several years ago. Also as one ages, the natural production of melatonin reduces, and can impact length of sleep. But that is another debate with all sort of issues that I have researched, but that opens "Pandora's box" which would lead to a dead end. I will close this paragraph firmly shut. Just a couple of points on the set-up of your graphs. It may be helpful to trim the ranges of some of the "y values" to get a better detailed view, eg. Flow limitations max say Flow limitations max 0.30 instead of 1.0. Flow rate. 100 max, instead of 120. This is of course just cosmetic stuff, but worth looking at to fine tune things.

Expat31,
I adjusted my OSCAR flow limit and flow rate as you suggested. Last night I raised my pressure to 12cm and 3 EPR, Wasn't any better than the 10cm and 3 EPR, so I am going to leave my settings there for a time and see how it goes. Thanks again for all your help. Old Steve

Hi Steve,
I found the page I was looking for. http://www.apneaboard.com/wiki/index.php...ng_therapy I would like to see the OSCAR. The last two OSCARS have similar 95% pressures. If you set pressure around might be good for you if the pressure change, flow limitation is disturbing you. Not machine related but just important for me on my quest for deeper sleep is trying to follow good sleep hygiene. I am working on medication timing. Unfortunately, consistent bedtime is a work in progress. Covering my eyes was a big surprise at the difference it made. I spent my second night with a weighted blanket, so far so good, I will give it more time before saying it was a success.
